The element aluminum forms a cation with the charge of +3. The symbol for this ion is Al³⁺, and the name is aluminum ion. The number of electrons in this ion 10.
<h3>What are ions?</h3>
Ions are formed when an atom gains or loses electrons.
Metals form positive ions by a loss of electrons whereas non-metals form negative ions by gaining electrons.
The aluminum ion is formed when aluminum loses three electrons to form Al³⁺ ion which has 10 electrons.
in conclusion, ions are formed by a gain or loss of electrons.

Answer:
Option D. 0.9mol x 2mol Fe /3mol CO2 x 55.845g Fe /1mol Fe
Explanation:
The balanced equation for the reaction is given below:
3CO + Fe₂O₃ → 2Fe + 3CO₂
Molar Mass of Fe = 56g/mol
From the balanced equation above,
3 moles of CO2 produced (2 mol Fe x 55.845g Fe.
Therefore, 0.9 mole of CO2 will produce = 0.9mol x 2mol Fe /3mol CO2 x 55.845g Fe /1mol Fe
Answer: when you burn something every action has a reaction. so if you put wood in the fire the wood would burn up into this coal like block once completely burnt through. after there is no more wood left to burn the fire would slowly die and there would just be the remains of the wooden block.
Answer: sulfuric acid
Explanation:
sulfuric acid always produces salts that end in sulfate and contain the sulfate ion, SO.
The formula for hydrocarbon is CnH(2n+2).
